limits and trigonometric functions

[Guest]

Hello everyone , I hope that you will be able to help me

I need to calculate this limit

[tex]\lim_{x \to 0}x[/tex] COS(((1-COS(X)/(X^2))2pi)

thanks in advance ^^

You have 5 left parentheses and only 4 right parentheses. Please correct that so we know what your function is!

Much of that is irrelevant! cos(anything) lies between -1 and 1 so as x goes to 0, x times cos(anything) goes to 0.
